2.3 Safety distance to transmitter antenna

2.3.1 Safety distance between transmitter antenna and personnel

For antenna configurations where it is possible to be briefly or constantly within the transmission range of the antennas, as in loading ramps, for example, minimum distances must be maintained.

Limits

The ICRP (International Commission of Radiological Protection) has worked out limit values for human exposure to HF fields that are also recommended by the ICNIRP (International Commission of Non Ionizing Radiological Protection). In German legislation on emissions (since 1997), the following limit values apply. These can vary according to frequency:

Frequency f [MHz] Electrical field strength E [V/m] Magnetic field strength H [A/m] 10 - 400 27,5 0,073 400 - 2.000 1.375 x f

2.000 - 300.000 61 0,16

1/2

0.0037 x f

1/2

The limit values for the 900 MHz reader antenna alternating field are thus:

Electrical field strength: E = 41.25 V/m

Magnetic field strength: H = 0.111 A/m

HF power density: E x H = 4.57 W/m

2.3 Safety distance to transmitter antenna

2.3.2 Minimum distance to antenna in accordance with ETSI

Minimum distance to antenna in accordance with ETSI (EU, EFTA, Turkey)

At a transmission frequency of 900 MHz, the wavelength of the electromagnetic wave λ is approximately 0.34 m. diminishes exponentially to the power three over distance, and for distances greater than 1 λ, it diminishes exponentially to the power two over distance.

For distances less than 1 λ in the near field, the electrical field strength

The horizontal line at 41.25V/m marks the "safety limit value".

For the maximum permisisble transmission power in accordance with ETSI (2W ERP), the "safety distance" d =

0.24 m. This means that personnel should not remain closer than 24cm to the transmitter antenna for extended periods (more than several hours without interruption). Remaining within the vicinity of the antenna for a brief period, even for repeated periods (at a distance < 0.24 m), is harmless according to current knowledge.

2.3 Safety distance to transmitter antenna

Note Reduced maximum radiated power with RF620R/RF630R readers

The SIMATIC RF620R (ETSI) reader has a maximum radiated power of 0.5 W ERP. The maximum safety distance is therefore 0.12 m.

The SIMATIC RF630R (ETSI) reader has a maximum transmitter power of 0.5 W. The radiated power therefore depends on the antenna cable and the type of antenna used, but must not exceed the 2 W ERP.

2.3.3 Minimum distance to antenna in accordance with FCC (USA)

Minimum distance to antenna in accordance with FCC (USA)

For the maximum permisisble transmission power in accordance with FCC (4W EIRP), the "safety distance" d = to the transmitter antenna for extended periods (more than several hours without interruption). Remaining within the vicinity of the antenna for brief period, even repeated periods (at a distance < 0.26 m) is harmless to health according to current knowledge.

4.1 Overview

You should observe the following criteria for implementation planning:

● Possible system configurations

● Antenna configurations

● Environmental conditions for transponders

The response of electromagnetic waves in the UHF band

●

● Regulations applicable to frequency bands

● EMC Directives

4.2 Possible system configurations

The SIMATIC RF600 system is characterized by a high level of standardization of its components. This means that the system follows the TIA principle throughout: Totally Integrated Automation. It provides maximum transparency at all levels with its reduced interface overhead. This ensures optimum interaction between all system components.

The RF600 system with its flexible components offers many possibilities for system configuration. This chapter shows you how you can use the RF600 components on the basis of various example scenarios.

4.2.1 Scenario for incoming goods

This example scenario shows the incoming goods bay of a warehouse. Pallets of goods are delivered through the incoming goods portal of a warehouse. Each pallet is equipped with a

tag. The tags contain user data that provide information about the sender and receiver of the goods. These data are read out and routed on.

Figure 4-1 Incoming goods bay

Features of the scenario

In this example, the maximum number of 4 antennas of the SIMATIC°RF660A type are connected to the SIMATIC°RF670R reader. The four antennas are aligned with one read point and therefore form a portal that is to be monitored. The reading ranges depend on the size of the portal as well as the density of readers.

The tags in this scenario are Smart Labels of type SIMATIC°RF630L. They are usually attached to a non-metallic base such as wooden crates or cartons, in which the goods are packed. The tags can be mounted in almost any position on the packaging or pallet.

The tags are read with the "Bulk reading" procedure in the incoming goods bay, i.e. a large number of items and many tags can be acquired at once. High read rates can be achieved in this manner.

conveyor

The The RFID tag is, however, always applied to the transport containers with the same alignment. The tags in this scenario are transponders of type SIMATIC RF620T.

The conveyor has a maximum width of 80 cm in this example. The transport velocity is up to 2 m/s. With this arrangement only a single RFID tag has to be detected each time (single-tag).

In this scenario a SIMATIC RF630R is used as the reader. Optimum reading reliability is ensured by two external SIMATIC RF660A antennas in a portal arrangement. Where the distances to, or between, the materials containers are extremely short the SIMATIC RF620A is an excellent alternative. The SIMATIC°RF630R reader reads the information from the tags on the transport containers and transfers it via a communication module to the SIMATIC S7 controller which controls the process in accordance with the tag information.

4.2 Possible system configurations

A typical characteristic of

modern manufacturing scenarios is their multitude of variations. The individual data and production steps are stored in the tag of a toolholder or product. These data are read by the machining stations during a production process and, if necessary, tagged with status information. This can be used to dynamically identify which production step is the next in the series. This has the advantage that the production line can work automatically without the need to access higher system components. The use of RFID therefore increases the availability of the plant.

In this scenario, bulk acquisition is necessary because several objects must be detected at the same time.

The SIMATIC RF630R reader uses two external antennas in a portal arrangement to read the information from the tags on the passing items and transfers it to the SIMATIC S7 controller via a communication module. The SIMATIC S7 controls the separating filter of the conveyor system depending on the tag information.

If only one simple evaluation of the tag ID is required, and the data will not undergo further processing, the SIMATIC RF670R offers this function without interfacing to the controller.

4.3.6 Reading range

The reading range between the reader (antenna) and the transponder is affected by the following factors:

The reading range depends on Description Transmit power of the reader The higher the transmit power of the reader, the larger the

reading range.

Tag size and type The larger the tag antenna, the larger the power input area

and therefore the larger the reading range.

Absorption factor of the materials The higher the absorption of the surrounding material, the

smaller the reading range.

Production quality of the tag The better the tag has been matched to the operating

frequencies during manufacturing, the greater the reading range.

Reflection characteristics of the environment

In a multiple-reflection environment (e.g., in rooms with reflecting surfaces, machinery, or concrete walls), the reading range can be significantly higher than in a lowreflection environment.

You will find detailed information about the reading range of the individual readers in the "Technical specifications" in the sections for the various readers.

In accordance with EPC Global as well as ETSI EN 302 208 V1.2.1, the four transmit channels are used for transmission with the RF670R, with the RF660R in Firmware Version V1.3 and higher, and with the RF620R/RF630R (see Section Regulations for UHF frequency bands in Europe (ETSI EN 302 208 V1.2.1) (Page 54)) and the tag response appears on the associated neighboring channels. As a result of the large difference in level between the transmitter channels and the tag response channels, this technology provides great advantages for frequency reuse. However, a prerequisite is that a certain minimum distance, and thus minimum decoupling, is observed between the antennas of adjacent readers.

In accordance with EPC Global as well as ETSI EN 302 208 V1.1.1, only the even channels are used for transmitting in this mode (communications path Reader -> Tag) with the RF660R in Firmware Version V1.2 and below; the tag response is on the odd channels as a result of the frequency offset.

4.3.7.3 Optimization of robustness of tag data accesses for readers that are operated simultaneously

Parameter data access reliability

If several readers are to be operated simultaneously in an environment, then the following settings affect the reliability of the reader's access to transponder data:

● Electromagnetic environment (see Chapter UHF band (Page 51))

● Type of transponder (see chapter Transponder/tags (Page 205))

● Number of transponders to be detected by an antenna at a time

● Type of antenna (see Chapter Antennas (Page 153), Chapter Guidelines for selecting RFID UHF antennas (Page 181), and Chapter Planning application (Page 84))

● Transponders' distance from and orientation toward antennas (see Chapter Transponder/ tags (Page 205))

● Distances and orientation of antennas of different readers to each other

● Radiated power of antennas

The robustness of tag data accesses is improved for readers whenever distances to adjacent readers are increased, radiated power is reduced, and a channel plan (for ETSI readers) is implemented. Adjacent readers are parameterized in the channel plan such that they cannot use the same channels.

A channel plan can be created for ETSI readers; for FCC readers, it is assumed that the probability of two readers accidentally using the same channel is very low.

SIMATIC RF620R reader

The RF620R has an integrated, circular polarized antenna. This means that the type of antenna cannot be freely selected.

Note Rotation of the reader through 90° around the z axis

the effects on adjacent readers can be reduced by rotating

SIMATIC RF670R, RF630R or RF660R reader with SIMATIC RF660A antenna

The electrical opening angles (vertical and horizontal) of the RF660A antenna are identical. Therefore, the robustness of the readers' access to transponder data cannot be optimized further by rotating them around the antenna axis.

Application example for RF620R/RF630R

The following example explains measures for enhancing the data access security from the RF620R reader to transponders:

● The antennas are placed next to each other and are aligned in parallel (see arrangement B in Chapter Dense Reader Mode (Page 46

● Radiated power is limited to 27 dBm (ERP) or 500 mW (ERP).

● The RF620R readers have been rotated through 90° around the z axis.

In addition, the following characteristics are to be fulfilled:

● Length of data to be read/written on the transponder: 99,99%

● Length of data to be read/written on the transponder: 512 bits (64 bytes)

With this technique which is only applicable to ETSI, the reader checks whether the relevant channel is assigned before transmission to prevent collisions. The reader will only transmit when this channel is free. The reader can transmit for up to 4 seconds on this channel and must then either pause for at least 100 milliseconds or jump immediately to an unassigned channel where it can transmit for another 4 seconds.

With the new ETSI EN 302 208 standard V1.2.1 this technique must be not be used (see Chapter Regulations for UHF frequency bands in Europe (ETSI EN 302 208 V1.1.2) (Page 57) and Chapter Regulations for UHF frequency bands in Europe (ETSI EN 302 208 V1.2.1) (Page 54) ).

4.4 Environmental conditions for transponders/tags

4.4.1 Basic rules

The transponder/tag must not be placed directly on metal surfaces or on containers of liquid. For physical reasons, a minimum distance must be maintained between the tag antenna and conductive material. A minimum distance of 5 cm is recommended. The tag operates better when the distance is greater (between 5 and 20 cm).

● Tag assembly on non-conductive material (plastic, wood) has a tendency to be less critical

than assembly even on poorly conductive material.

● The best results are achieved on the materials specified by the tag manufacturer.

● You can obtain more detailed information from the tag manufacturer.

4.5 The response of electromagnetic waves in the UHF band

4.5.1 The effect of reflections and interference

Reflections and interference

Electromagnetic waves in the UHF band behave and propagate in a similar manner to light waves, that is they are reflected from large objects such as ceilings, floors, walls and windows and interfere with each other. Due to the nature of electromagnetic waves, interference can lead to wave amplification which can produce an increased reading range. In the worst case,

4.5 The response of electromagnetic waves in the UHF band

interference can also result in waves being extinguished which causes holes in reader coverage.

Reflections can also be objects to a certain extent (deflection). This can increase the reading probability.

Due to these electromagnetic characteristics, it is extremely difficult in the multiple-reflection environment that is usually found in the real environment on site, to determine propagation paths and field strengths for a particular location.

beneficial when they cause electromagnetic waves to be routed around

Reducing the effect of reflections/interference on tag identification

● Reducing the transmit power: To reduce interference to a minimum, we recommend that the transmitter power of the reader is reduced until it is sufficient for an identification rate of 100%.

● Increasing the number of antennas to 3 or 4: More antennas in a suitable antenna configuration can prevent gaps in reader coverage.

4.5.2 Influence of metals

Metal can have an effect on the electromagnetic field depending on the arrangement or environment. The effect ranges from a hardly determinable influence through to total blocking of communication. The term metal in this context also includes metallized materials that are either coated with metal or shot through with metal to such an extent that UHF radiation cannot penetrate or only to a minimal extent.

The effect of metal on the electromagnetic field can be prevented as follows:

● Do not mount tags on metal.

● Do not place metallic or conducting objects in the propagation field of the antenna and transponder.

Tags mounted directly onto metal

In general, tags must not be mounted directly onto metallic surfaces. Due to the nature of the magnetic field, a minimum distance must be maintained between the tag antenna and conductive materials. For further details on the special case of attaching transponders to electrically conducting materials, see Section SIMATIC RF620T (Page 235) and SectionSIMATIC RF640T (Page 271) .

In the case of transponders that are not designed for mounting on metallic materials, the minimum permissible distance from metal is 5 cm. The larger the distance between the transponder and the metallic surface, the better the function of the transponder.

4.5.3 Influence of liquids and non-metallic substances

Non-metallic substances can also affect the propagation of electromagnetic waves.

SIMATIC RF600

System Manual, 06/2010, J31069-D0171-U001-A10-7618

Draft Version 02.06.2010

When non-metallic substances or objects are located in the propagation field that can absorb UHF radiation, these can even extinguish the field entirely.

The high-frequency damping effect of water and materials with a water content, ice and carbon is high. Electromagnetic energy is partly reflected and absorbed.

Liquids and petroleum-based oils have low HF damping. Electromagnetic waves penetrate the liquid and are only slightly weakened.

alter the antenna field depending on their size and distance and can

4.5.4 Influence of external components

The R&TTE guideline and the relevant standards govern the electromagnetic compatibility requirements. This also concerns the external components of the RF600 system. Even though the requirements for electromagnetic compatibility have been specified, various components will still interfere with each other.

The performance of the RF600 system is highly dependent on the electromagnetic environment of the antennas.

RF600 system planning

4.6 Regulations applicable to frequency bands

Reflections and interference

On the one hand, antenna fields will be weakened by absorbing materials and reflected by conducting materials. When electromagnetic fields are reflected, the antenna field and reflecting fields overlap (interference).

External components in the same frequency band

On the other hand, external components can transmit on the same frequency band as the reader. Or the external components can transmit in different frequency bands with side bands that overlap with the frequency band of the reader. This results in a reduction of the "signal-tonoise" ratio which reduces the performance of an RF600 system.

If a DECT station that is transmitting in the 2 GHz band, for example, is located in the receiving range of an antenna of the RF600 system, the performance of the write and read accesses to the transponder will be affected.

Reasons for interference

The following reasons may cause the interference:

● Only four transmission channels (865.7; 866.3; 866.9; 867.5 MHz) are now available

● Deactivation of Listen Before Talking (LBT)

● When operating readers in mixed mode according to the old ETSI standard

The RF620R (ETSI) and RF630R (ETSI) readers support both ETSI standards EN 302 208 V1.1.1 and V1.2.1 (max. 4 channels without LBT). As of January 2010, these readers must be operated using the 4-channel plan and without LBT.

RF660R

RF660R readers V1.2 or earlier firmware versions exclusively use a radio profile according to EN 302 208 V 1.1.1 (max. 15 channels with LBT).

RF660R readers V1.3 or later firmware versions exclusively use a radio profile according to EN 302 208 V1.2.1(max. 4 channels without LBT).

4.7.3.2 Preventing interference in mixed operation

You ensure problem-free operation by a strict separation in the assignment of transmission and receive channels of the RF600 readers according to EN 302 208 V1.1.1 and EN 302 208 V1.2.1. This means that neither the transmission channels nor the receive channels of the readers operated according EN 302 208 V1.1.1 must overlap with the transmission or receive channels of the readers operated according to EN 302 208 V1.2.1.

Procedure

1. In the channel plan, for all readers that are not to operated in dense mode (EPC Global Class 1 Gen 1, EPC Global Class 1 Gen 2 (no dense mode)) or ISO 18000-6B).

2. For all readers that are to operate in dense mode (EPC Global Class 1 Gen 1, EPC Global Class 1 Gen 2 (dense mode)), mark the transmission channels and the channels right next to them (receive channels) as assigned channels of a reader.

3. For this purpose, first mark all transmission channels and any adjacent receive channels in dense mode operation of the R660R readers for V1.3 or later versions in the channel plan. In mixed operation, the RF660R reader operated according to EN 302 208 V1.1.1 can use more channels than an RF660R reader operated according to EN 302 208 V1.2.1.

only mark the transmission channels as assigned channels of a reader

4. Then mark all transmission channels and any adjacent receive channels in dense mode operation of the R660R readers for V1.2 or earlier versions in the channel plan.

Example of planning a channel plan

RF600 system planning

Below you will find

a concrete example of a channel plan with which you prevent interference:

● New readers operating according to EN 302 208 V1.2.1 must use channels with a channel

number below 107. Dense mode can be activated or deactivated.

● Readers according to the old standard EN 302 208 V1.1.1 can use channels with a channel

number between 109 and 114. If dense mode is activate, only even-numbered channels can be used.

Such a setting prevents that readers interfere with each other. At which channel number the separation will be depends on the ratio of readers according to the old standard and new standard. This limit can be shifted as required.

4.8 Guidelines for electromagnetic compatibility (EMC)

4.8.1 Overview

These EMC Guidelines answer the following questions:

Why are EMC guidelines necessary?

●

What types of external interference have an impact on the system?

How can interference be prevented?

●

How can interference be eliminated?

SIMATIC RF600 System Manual, 06/2010, J31069-D0171-U001-A10-7618

RF600 system planning

Draft Version 02.06.2010

4.8 Guidelines for electromagnetic compatibility (EMC)

● Which standards relate to EMC?

● Examples of interference-free plant design

The description is intended for "qualified personnel":

● Project engineers and planners who plan system configurations with RFID modules and have to observe the necessary guidelines.

● Fitters and service engineers who install the connecting cables in accordance with this description or who rectify defects in this area in the event of interference.

NOTICE

Failure to observe notices drawn to the reader's attention can result in dangerous conditions in the plant or the destruction of individual components or the entire plant.

4.8.2 What does EMC mean?

The increasing use of electrical and electronic devices is accompanied by:

● Higher component density

● More switched power electronics

● Increasing switching rates

Lower power consumption of components due to steeper switching edges

●

The higher the degree of automation, the greater the risk of interaction between devices.

Electromagnetic compatibility (EMC) is the ability of an electrical or electronic device to operate satisfactorily in an electromagnetic environment without affecting or interfering with the environment over and above certain limits.

EMC can be broken down into three different areas:

● Intrinsic immunity to interference: immunity to internal electrical disturbance

● Immunity to external interference: immunity to external electromagnetic disturbance

● Degree of interference emission: emission of interference and its effect on the electrical environment

All three areas are considered when testing an electrical device.

The RFID modules are tested for conformity with the limit values required by the CE and RTTE guidelines. Since the RFID modules are merely components of an overall system, and sources of interference can arise as a result of combining different components, certain guidelines have to be followed when setting up a plant.

EMC measures usually consist of a complete package of measures, all of which need to be implemented in order to ensure that the plant is immune to interference.

4.8 Guidelines for electromagnetic compatibility (EMC)

Note

The plant manufacturer is responsible for the observance of the EMC guidelines; the plant operator is responsible for radio interference suppression in the overall plant.

All measures taken when and interference suppression measures.

The plant operator must comply with the locally applicable laws and regulations. They are not covered in this document.

4.8.3 Basic rules

It is often sufficient to follow a few elementary rules in order to ensure electromagnetic compatiblity (EMC).

The following rules must be observed:

Shielding by enclosure

● Protect the device against

housing or enclosure must be connected to the chassis ground.

setting up the plant prevent expensive retrospective modifications

external interference by installing it in a cabinet or housing. The

● Use metal plates to shield against electromagnetic fields generated by inductances.

● Use metal connector housings to shield data conductors.

Wide-area ground connection

● Bond all passive metal parts to chassis ground, ensuring large-area and low-HF-impedance

contact.

● Establish a large-area connection between the passive metal parts and the central

grounding point.

● Don't forget to include the shielding bus in the chassis ground system. That means the

actual shielding busbars must be connected to ground by large-area contact.

● Aluminium parts are not suitable for ground connections.

Plan the cable installation

● Break the cabling down into cable groups and install these separately.

● Always route power cables, signal cables and HF cables through separated ducts or in

separate bundles.

● Feed the cabling into the cabinet from one side only and, if possible, on one level only.

● Route the signal cables as close as possible to chassis surfaces.

● Twist the feed and return conductors of separately installed cables.

RF600 system planning

Draft Version 02.06.2010

4.8 Guidelines for electromagnetic compatibility (EMC)

● Routing HF cables: avoid parallel routing of HF cables.

● Do not route cables through the antenna field.

Shielding for the cables

● Shield the data cables and connect the shield at both ends.

● Shield the analog cables and connect the shield at one end, e.g. on the drive unit.

●

Always apply large-area connections between the cable shields and the shielding bus at the cabinet inlet and make the contact with clamps.

● Feed the connected shield through to the module without interruption.

● Use braided shields, not foil shields.

Line and signal filter

● Use only line filters with metal housings

● Connect the filter housing to the cabinet chassis using a large-area low-HF-impedance connection.

● Never fix the filter housing to a painted surface.

● Fix the filter at the control cabinet inlet or in the direction of the source.

4.8.4 Propagation of electromagnetic interference

Three components have to be present for interference to occur in a system:

● Interference source

● Coupling path

● Interference sink

Figure 4-15 Propagation of interference

If one of the components is missing, e.g. the coupling path between the interference source and the interference sink, the interference sink is unaffected, even if the interference source is transmitting a high level of noise.

The EMC measures are to interference. When setting up a plant, the manufacturer must take all possible measures in order to prevent the occurrence of interference sources:

● Interference suppression measures must be introduced on all interference-emitting

● The design of the system must be such that mutual interference between individual

Information and tips for plant design are given in the following sections.

Interference sources

In order to achieve a high level of electromagnetic compatibility and thus a very low level of disturbance in a plant, it is necessary to recognize the most frequent interference sources. These must then be eliminated by appropriate measures.

4.8.5 Prevention of interference sources

●

Missing or incorrectly connected shield

● Inappropriate physical arrangement of cables

● Missing or incorrect earthing

● Inappropriate physical arrangement

● Components not mounted securely Unfavorable cabinet configuration

●

A high level of switched inductances are frequent sources of interference in plants.

Suppression of inductance

Relays, contactors, etc. generate interference voltages and must therefore be suppressed using one of the circuits below.

Even with small relays, interference voltages of up to 800 V occur on 24 V coils, and interference voltages of several kV occur on 230 V coils when the coil is switched. The use of freewheeling diodes or RC circuits prevents interference voltages and thus stray interference on conductors installed parallel to the coil conductor.

immunity to interference can be achieved by avoiding interference sources. All

Draft Version 02.06.2010

4.8 Guidelines for electromagnetic compatibility (EMC)

Note

All coils in the cabinet should be suppressed. The valves and motor brakes are frequently forgotten. Fluorescent lamps in the control cabinet should be tested in particular.

4.8.6 Equipotential bonding

Potential differences between different the plant components and different voltage levels. If the plant components are connected across signal cables, transient currents flow across the signal cables. These transient currents can corrupt the signals.

Proper equipotential bonding is thus essential.

● The equipotential bonding conductor must have a sufficiently large cross section (at least 10 mm2).

● The distance between the signal cable and the associated equipotential bonding conductor must be as small as possible (antenna effect).

● A fine-strand conductor must be used (better high-frequency conductivity).

● When connecting the equipotential bonding conductors to the centralized equipotential bonding strip (EBS), the power components and non-power components must be combined.

parts of a plant can arise due to the different design of

● The equipotential bonding conductors of the separate modules must lead directly to the equipotential bonding strip.

Figure 4-18 Equipotential bonding (EBS = Equipotential bonding strip)

The better the equipotential bonding in a plant, the smaller the chance of interference due to fluctuations in potential.

SIMATIC RF600

System Manual, 06/2010, J31069-D0171-U001-A10-7618

Draft Version 02.06.2010

Equipotential bonding should not be confused with protective earthing of a plant. Protective earthing prevents the occurrence whereas equipotential bonding prevents the occurrence of differences in potential.

4.8.7 Cable shielding

Signal cables must be shielded in order to prevent coupling of interference.

The best shielding is achieved by installing the cables in steel tubes. However, this is only necessary if the signal cable is routed through an environment prone to particular interference. It is usually adequate to use cables with braided shields. In either case, however, correct connection is vital for effective shielding.

Note

An unconnected or incorrectly connected shield has no shielding effect.

As a rule:

RF600 system planning

4.8 Guidelines for electromagnetic compatibility (EMC)

of excessive shock voltages in the event of equipment faults

● For analog signal cables, the shield should be connected at one end on the receiver side

● For digital signals, the shield should be connected to the enclosure at both ends

● Since interference signals are frequently within the HF range (> 10 kHz), a large-area HF-

proof shield contact is necessary

Figure 4-19 Cable shielding

The shielding bus should

be connected to the control cabinet enclosure in a manner allowing good conductance (large-area contact) and must be situated as close as possible to the cable inlet. The cable insulation must be removed and the cable clamped to the shielding bus (highfrequency clamp) or secured using cable ties. Care should be taken to ensure that the connection allows good conductance.

5.1.2.4 Interpretation of directional radiation patterns

The following overview table will help you with the interpretation of directional radiation patterns.

The table shows which the radiated power depending on the reference angle from the directional radiation patterns, and thus obtain information on the read/write range with this reference angle with regard to a transponder.

The dBr values correspond to the difference between the maximum dBi value and a second dBi value.

-6 50

-9 35

-12 25

-15 18

-18 13

dBi values correspond to which read/write ranges (in %): You can read

7.3 dBic ± 0.5 dB

Example

As one can see antenna gain is 0 dB. In the Azimuth diagram, the antenna gain falls by 3°dB at approximately ± 39°. Therefore the dBr value is -3. The antenna range is only 50% of the maximum range at ± 39° from the Z axis within the horizontal plane.
